Abstract

PURPOSE:To make structure of a blow-off opening simple without making a part of a main body of the blow-off opening into double structure, by a method wherein a control plate of an air flow direction is provided on a nozzle part, which is connected by a connecting rod with a deflection plate in relation to a changeover device of the air flow direction of an air conditioner. CONSTITUTION:A blow-off air flow deflected through action of an inclination of a control plate 4 of an air flow direction and a nozzle part 3 flows along an inner wall of a main body 1. Now, supposing that the air has flowed along the inner wall of the left side of the main body 1, the control plate 4 of the air flow direction is inclined and a left side deflection plate 5 is apt to receive air pressure. The control part 4 of air flow direction is tilted along with the left side deflection plate 5, and the blow-off air flow flows along the inner wall of the right side of the main body 1. A right side deflection plate 6 is turned into a state which is apt to receive air pressure, tilted by receiving the air pressure of the air flow flowing along the inner wall of the right side of the main body 1, and the air flow direction is changed over by moving the control plate 4 of the air flow direction.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a wind direction switching device such as an air conditioner, and by providing a wind direction control plate in a nozzle part and connecting the wind direction control plate to a connecting rod, the wind direction control plate can be controlled. The purpose is to link the operation with the operation of the wind direction control plate so that the blowout flow can be automatically switched depending on the inclination of the wind direction control plate.

As shown in FIG. 4, a conventional wind direction switching device for an air conditioner or the like is provided with control ports 10 on the left and right sides of a nozzle part, a wind direction plate 11 that is operated by the wind pressure of the blowout flow, and a left and right static switch connected to the control ports 10. The pressure port 12 was opened and closed, and the airflow direction was changed based on the pressure difference between the left and right control ports 10. In this method, in order to create the control port 10 and the static pressure port 12, a control section having a double structure in a part of the outlet body must be provided, which has the disadvantage that the outlet structure becomes complicated.

The present invention solves the above-mentioned conventional drawbacks, and embodiments thereof will be described below with reference to FIGS. 1 to 3.

In the figure, reference numeral 1 denotes a main body (hereinafter referred to as main body) of a wind direction switching device installed at the outlet of an air conditioner 2, which is formed so that the air flow spreads from side to side. 3 is a nozzle part provided in the main body 1 for increasing the blowing flow velocity, and 4 is a wind direction control plate provided in the nozzle part 3, which is movable according to the wind flow. Reference numeral 5 denotes a left wind direction plate which is movable by the air flow flowing along the left inner wall of the main body 1, and is movably supported near the discharge port side of the main body 1. Reference numeral 6 denotes a right wind direction plate which is movable by the air flow flowing along the right inner wall of the main body 1, and is movably supported near the discharge port side of the main body 1.

7 is a connecting rod that connects the wind direction control board 4 and the left wind direction board 5;
8 is a connecting rod that connects the left wind direction plate 5 and the right wind direction plate 6.

In the above configuration, the inclination of the wind direction control plate 4 and the nozzle part 3
The blowout flow deflected by the action of the constriction section then flows along the inner wall of the main body 1. Assuming that the current wind is flowing along the left inner wall of the main body 1, the wind direction control plate 4 will be tilted, and the left wind direction plate 5 will be in a state where it is most susceptible to wind pressure, facing the wind flow, as shown by the solid line in Fig. 2. . As a result, the left wind direction plate 5 tilts due to the wind pressure, and the series of connecting rods 7
The wind direction control plate 4 is tilted as shown by the dashed line, and the air flow is caused by the wind direction control plate 4 to flow along the right inner wall of the main body 1. At this time, the right wind direction plate 6 moves via the connecting rod 8 as the left wind direction plate 5 tilts in response to wind pressure, and is in a state where it faces the wind flow and is most susceptible to wind pressure.

Therefore, the right side wind direction plate 6 is tilted to receive the wind pressure of the air flow flowing along the right side inner wall of the main body 1, and the wind direction control plate 4 is movable as shown by the solid line in FIG. 2 to change the wind direction.

In this way, the wind direction is switched from side to side within the main body 1.

As described above, according to the present invention, the wind direction plate operated by the wind pressure of the blowout flow and the wind direction control plate that switches the wind direction are provided in the main body of the wind direction switching device, and the connecting rod connects the wind direction plate and the wind direction control plate. In particular, since the inclination of the wind direction control plate is changed by the wind pressure of the blowout flow, and the direction of the blowout air is switched, a conventional control section is not required and the main body structure is simplified.
